【Tunnel Construction】
The underground passage will be built at the the tunnel which is in the southern section of Italian brenner baseline.

Recently,Italy will build a underground passage across Isarco River in the south of Iralian brenner baseline.This project cost 300 Euro.And it will come into operation at the last half year.Maybe it will continue eight years.

The tunnel of Sarkozy Tunnel located at the southern tip of brenner baseline tunnel.It is the last part of the whole project.The whole line contained two main tunnels which is 4.3 kilometres and two interconnecting tunnels which is 2.3 kilometers.The four tunnels across the Isarco River,Autoroute A22,Autoroute SS12 and Verona-brenner rail line respectively.

ZZHZ is specialize this field for many years.The concrete spraying system is our main product.And it is widely used in the underground engineering,geotechnical ingineering and municipal ingineering.With the concrete pump and free mechanical arm as the main parts of the machine,it can spray the concrete to form the supporting layer in the tunnel by compressing the air.
